It means that socket shutdown failed.
Do you have firewall between mod_jk and JBoss or some non-standard
network driver (e.g running under some VM)?
This can cause network FIN packet not getting transmitted over it
since we issued socket shutdown, but the other side didn't react on
that message.

What kind of connector is on the JBoss side. Java or APR?
